Title: Coupling for short Archimedean screws which operate on a cantilever shaft in the body of trucks equipped for shredding and mixing fibrous fodder used as animal feed
Inventor: LANZANOVA SERGIO
IPC: A01F/
Filed: 1990-10-25
Granted: 1994-05-18
Abstract: The subject of the present invention is a new way of keeping the upper Archimedean screws, found inside the body of trucks equipped for shredding and mixing fibrous and non-fibrous fodder and used in the uniform distribution of livestock feed, rotating and connected together. These screws, which are short and cantilevered, operate within the truck body and help to agitate, shred, chop and mix the different types of fodder that are introduced into the truck body to be prepared and distributed as feed to farm animals. The said coupling for Archimedean screws consists of a suitably designed unit made up of robust elements that are capable of withstanding the stresses to which the said rotating units will be subjected as they carry out the work they are intended to perform. By virtue of the characteristic solution which it embodies and which enables it to work efficiently, the said invention constitutes an effective device which solves the breakdown problems that affect the shafts and supports of the said short and cantilevered Archimedean screws. <IMAGE>

Title: Carrier, particulary for several bottles
Inventor: HANSEN FINN R
IPC: B65D71/46
Filed: 1994-08-03
Abstract: The bottle holder (10, 10<1>) is designed to take and transport bottles (2), which are placed in a row. The bottles (2) have a neck (3), which becomes conically narrower towards the top; the upper end (7) of it has an outside thread for a screw-cap (8) or a ring for pressing the cap. The holder is made out of a sheet of corrugated cardboard (1, 1<1>), which has five longitudinal sections, namely in the central section (11, 11<1>), to the longitudinal ends of which, the medium sections (12, 12<1> and 13, 13<1>) are attached, and two outer sections (14, 14<1> and 15, 15<1>) are attached to the medium sections. The sections are separated from one another by grooves (17) or similar, and have openings (20, 20<1>, 21, 21<1>), that are placed in a single row, as the sheet is deformed to form a closed profile, to which the neck (3) of the bottle (2) and a cap (8) are squeezed in. according to the description of the invention, the mentioned sheet and the holder in the central section(11, 11<1>), has jointed staples (27, 27<1>, 27<2>), and the medium sections (12, 12<1>, 13, 13<1>) have supportive staples (24, 24<1>, 24<2>). The staples are pressed towards the caps (8) of the bottles (2) or to the rim (4) or the outer section (14, 14<1>) and the neck (3). This neutralizes the respective movements between the bottle and the holder and ensures that both sides have coordination. Supportive staples fixate the jointed staples in their working positions.

Inventor: JULIJS BLANKS
IPC: B23Q3/06
Filed: 1997-10-07
Abstract: The offered device for sharpening the teeth on a hand-saw is designed in the form of wooden nippers and is characteristic in that the device consists of 2 tablets that form the jaw of the nippers A and B, and wedge nog C. Both the tablets - jaw of the nippers - are joined with a screw bolt D in a way that the jaws are moving over the circumference which ensures sufficiently stable fixing of the saw. The jaw of the nippers are joined only in one place with a screw, which divides the moving jaw in the proportion a:b = 2/5:3/5 (image 1). Sufficiently stable fixing of the saw is ensured by the jaw of the nippers which are made of tablets with a thickness of 2 cm, where the moving jaw A is 25 cm long and length a=10 cm, but b= 15 cm. The prolonged end of the static jaw B of the device can be fixed horizontally stock-still to the bench, which allows the saw to be sharpened in the sitting position.<IMAGE>

Title: Process for producing of furfural and acetic acid
Inventor: NIKOLAJS VEDERNIKOVS
IPC: C07D307/50
Filed: 1997-11-14
Abstract: Invention applies to the industrial obtainment of furfural and acetic acid from raw materials containing pentosanes, for instance, deciduous wood-pulp. Raw material is reduced to pieces of the size of technologic chips, dampened with salt or salt mixture, which by dissociation forms cations with a charge of at least two. Then the solution is treated under overheated water steam flow at the increased pressure. Steam that comes from the reactor and contains furfural, is condensed, thus acquiring secondary steam, which is used for extracting and purification of furfural and acetic acid with the rectification method, as well as for other purposes. The raw material being left over after treatment with water steam is unloaded from the reactor with the decompression method, in case of necessity - dehydrated by pressing and/or drying and used as fuel for obtaining technological steam and/or other purposes.

Title: Fremgangsmaate til behandling av smeltet metall.
Inventor: ECKERT CHARLES EDWARD
IPC: C22B9/05
Filed: 1983-01-05
Abstract: Smeltet aluminium eller andre metaller renses ved at man bringer metallet i kontakt med et fluorkarbon, såsom CClF, for å nedsette mengden av forurensnings-metallelementer sammen med gass og inneslutninger deri, fortrinnsvis i nærvær av en agiteringsinnretning for å øke effektiviteten. Et oksydasjonsmiddel, såsom oksygen, anvendes for å hindre karbonet i fluorkarbonet i å danne karbidinneslutninger. Oksydasjon av karbonet til karbonmonoksyd foretrekkes ved behandling av aluminium, da monoksydet effektivt fjerner karbonet fra systemet uten at aluminium oksyderes. Man anvender fortrinnsvis en fluorakseptor som temporært forbinder seg med fluoret i fluorkarbonet og hindrer det i å reagere med karbon, slik at fluoridet fortsatt er tilgjengelig for behandling av det smeltede metall. De gasser som anvendes for behandling av det smeltede metall, kan ledes over et sjikt av karbon umiddelbart før innføringen i smeiten. Systemet drives med liten skum/slam-dannelse og uten tilveiebringelse av et saltdekke og muliggjør praktisk talt røk-fri drift.

Abstract: A container, e.g. a feeding bottle, comprises a lining (2), Fig. 1 (not shown) the top or bottom of which may be formed with a nipple, and a surrounding sleeve (4) of relatively thicker material, e.g. of cardboard.  The lining of synthetic plastics, may be formed by vacuum or pressure into the required shape in a mould and subsequently inserted into the sleeve which, if it is of cardboard, is moistened to make it expand and shrink on to the lining on drying.  The lower end of the sleeve may be rolled inwards to form a flange, Figs. 4 and 7 (not shown).  The upper edge of the lining is flanged over the sleeve and may be closed by means of a disc (16), Fig. 3 (not shown), sealed to the flange, a gripping flap (7) enabling it to be torn off. Alternatively, Fig. 4 (not shown), the container, may be closed by a lensshaped lid (15) of plastics forming a tight joint within the upper end of the lining.  The container may have a sealing disc (16) at its upper end, Fig. 5 (not shown), and be opened by placing it over a hollow piercer (14), thereby draining the liquid contents through the base.

Abstract: 1350995 Toothed gearing; differential gear SKF INDUSTRIAL TRADING & DEVELOPMENT CO NV 29 June 1971 [30 June 1970] 30447/71 Headings F2Q and F2D In a motor-vehicle conventional type bevel differential gear 4 driven by the usual crown wheel 3 and pinion 6 from the usual propeller shaft (not shown), the pinion 6, pinion shaft 7, propeller shaft connecting flange 9 and roller bearings 15, 17 form a unit which after its assembly cannot be taken apart. As shown, when the parts are assembled together, finally putting the cylindrical sleeve 8 of flange 9 over the end of pinion shaft 7, the bearings 15, 17 are preloaded by compressing the flange 9 and pinion 6 towards each other such that when the correct preload is achieved the sleeve 8 and shaft 7 are permanently connected by electrobeam or spin welding. Fig. 2 (not shown) illustrates a similar but more compact version in which the flange (22) is formed with a sleeve (21) and is spigoted on the pinion shaft (20), the ball bearing races being directly formed in the surfaces of the pinion shaft and sleeve and in an outer housing (25, 26) shimmed and bolted to the main housing (27), the bearings being correctly pre-loaded when the shaft and sleeve are abutted and welded together. Figs. 3 to 5 (not shown) show various alternative arrangements in which the pinion and connecting flange are forged as one piece, the pre-loading of the bearings being effected by the insertion of the balls during assembly. Fig. 4 illustrates an arrangement in which the ball bearings are arranged at each end of the pinion teeth in a supporting housing having an opening through which the crown wheel engages the pinion. In Fig. 5 the pinion flange is formed as a yoke end for the propeller shaft universal joint.
